BUG: cannot move messages to root mailfolder in namespace "There can be only one namespace with inbox=yes"
by Marc Roos 09 Jan '19

09 Jan '19

I can only move messages to a root namespace folder when specifying inbox=yes. That is strange because it is not even the inbox. I don't even get why it is not by default possible, maybe bug there? You have made the mistake of overloading the use of a parameter inbox=yes (or not creating a parameter to tell folder can be used to move messages to), there is indeed only one folder that gets incoming messages delivered to, and that is the inbox=yes. You should have created a 2nd parameter specifying if a folder should be allowed to store mail. (I have been running this dovecot server for 20 years or so, and I am really surprised about still running into issues on such basic things as trying to put folders onto different storage. Not to mention the lack of help you can get here. Is there some roadmap, features implementation overview available? Can you make public issues on github?)

Hello, I am mosty done with the upgrade, but there is a problem that keeps me awake at night: file ownership and permissions. It would be most helpful to have the following from Aki's live system: ls -halFR /var/run/dovecot

Hello! dsync SSL still doesn't work for replication, so I've disabled it and tried to sync without. But I have a problem with temp directory. Is it possible to change path to temp folder? I don't want to set permissions but change temporary folder for replication.

Permission error on stats writer
by Matt Simpson 08 Jan '19

I’m running Dovecot 2.3.4 on FreeBSD 11.2 with qmail. In my mail log, I see messages like this on every delivery Jan 8 10:30:02 v1 qmail: 1546961402.314222 delivery 533: success: lda(matt,)Error:_net_connect_unix(/var/run/dovecot/stats-writer)_failed:_Permission_denied/did_0+0+1/ Searching for this error, I found a message on a support forum for a different server that suggested adding this to dovecot.conf: service stats { unix_listener stats-reader { user = vmail group = vmail mode = 0660 } unix_listener stats-writer { user = vmail group = vmail mode = 0660 } } The person reporting the error said that this corrected it. But since I’m running qmail, I have no vmail user/group. I’m guessing that I need to replace user/group with the values that some mail delivery process is running with. I’ve tried a couple of things with no success.

Apple mail fails with Submission
by Ruud Voorjans 08 Jan '19

08 Jan '19

Dear all, I'm running dovecot # 2.3.2.1 - Pigeonhole version 0.5.2 () - OS: Linux 4.18.0-12-generic x86_64 Ubuntu 18.10 with Submission. It works great except with apple mail (Iphone). I get an error with the MTA (postfix): ""postfix/submission/smtpd[32552]: warning: non-SMTP command from mail.example.org[xx.xx.xx.xx]: Content-Transfer-Encoding: 7bit"" with other mail-client(s) (Outlook (Desktop and Iphone app)) i have no problem and it proxy-sends the e-mail beautiful out to the recipient. I think it is some kind of bug or maybe it just isn't supported (yet), cause as you said it is still "pretty basic". Best Regards

Hi I have two server directors in ring and 5 dovecot servers (2.2.36) IP for IMAP and POP3 is a VIP (keepalived) What is the best solutions to get realy HA for 5 dovecot servers ? Maby corosync+pacemeker ? But this solution is too problematic and hardcore Why I need HA ? Doveadmin is too lazy and doveadm director does not know that one machine broke down and still sends traffic

Dovecot no logs by sieve user script
by Christian Wolf 07 Jan '19

07 Jan '19

Dear mailinglist, I have the problem that I had to migrate a setup and since then my user's sieve script does no longer log anything. I have sieve_user_log unset and sieve points to a folder (ready for ManageSievev service). In the old config I had sieve point to the symlink and sieve_dir point to the folder of all scripts. As sieve_dir is deprecated I use the sieve directive only (see below). According to my understanding of https://wiki2.dovecot.org/Pigeonhole/Sieve/ Configuration this should result in user logging in ~/.dovecot.sieve.log. This file is never generated by dovecot and if I create it manually, it is not filled. Can you tell me, what I am missing here in order to get the per-user logs running? Thank you very much Christian # dovecot --version # dovecot -n # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.9.0-8-amd64 x86_64 Debian 9.6 auth_mechanisms = plain login disable_plaintext_auth = no mail_location = maildir:~/Mailbox managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } postmaster_address = postmaster@wolf- stuttgart.net protocols = " imap sieve sieve" service auth { unix_listener /var/spool/postfix/ private/auth { mode = 0666 } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl = required ssl_cert = </etc/letsencrypt/live/imap/fullchain.pem ssl_key = # hidden, use -P to show it userdb { driver = passwd } userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol lda { mail_plugins = " sieve" }

special_use folders still created
by Marc Roos 07 Jan '19

07 Jan '19

dovecot-2.2.36-3.el7.x86_64 The below configuration seems to work for Thunderbird and emclient, when moving a message to Junk. Emclient uses "Junk E-mail" and Thunderbird uses "Junk". On the server is only the file .Junk created as expected. When I move a message to Archive in Thunderbird. On the server the files .Archives and .Archives.2018 are created (Thunderbird creates a subfolder in Archives) How is this possible? On the server there is already an .Archive folder so it should create .Archive.2018 not? imap_capability = +SPECIAL-USE # drafts folders merging mailbox Drafts { special_use = \Drafts auto = create } # archive folders merging mailbox Archive { special_use = \Archive auto = create } mailbox Archives { special_use = \Archive auto = no } # spam folders merging mailbox Junk { special_use = \Junk auto = create } mailbox Spam { special_use = \Junk auto = no } mailbox "Junk E-mail" { special_use = \Junk auto = no }

reprocessing mail
by Marc Lucke 06 Jan '19

06 Jan '19

Hey guys, I had some corruptions whereby dovecot would bomb out on mail files in my maildir. I found that if piped the files to dovecot-lda the all email was clean &lost. I even retrieved email I thought might have been lost for good. I have some better ideas now, but I still processed a few thousand emails like that now & would like to do something like this: * stop dovecot * iterate over each file ** get date ** touch date (linux - to set the date/time) ** rename the file with the correct epoch ** update dovecot-uidlist with correct epoch * start dovecot Will that work? Or is there something I've missed or should do? - Marc
